How long does puppyhood last?
Puppyhood in dogs shares many similarities to human childhood. Puppy development is made up of a few stages, and some dogs can mature faster than others. Many don’t realize it, but smaller dogs tend to mature faster than larger dogs. Smaller dogs usually reach adult size at approximately 12 months of age, while larger dogs tend to reach physical maturity at around 24 months.
Despite this, puppyhood in dogs is about much more than just physical growth. In addition to weight and height, you can measure puppyhood based on behavior and personality, or simply based on how long your dog remains looking like an adorable puppy.
Continue reading below to check out how long puppyhood lasts based on these various metrics:
Dog Breeds that Take Longer to Mature Physically
Did you know that large breeds of dogs take the longest to reach adult size? See some examples below:
Bullmastiff
Bullmastiff dogs can reach upwards of 100 pounds during adulthood. However, they do not reach their mature weight and size until they are about 2 years of age or older.
Females of the same breed have a slow growth, reaching their physical maturity between 18 to 20 months. Meanwhile, the males can continue to grow until they are almost 3 years old.
Before deciding to get a Bullmastiff, be prepared to deal with a growing, adolescent puppy for 2-3 years!
Saint Bernard
The Saint Bernard is another large breed of dog that takes a long time to reach its adult size. They usually take 2 to 3 years to mature both physically and mentally.
Chances are you’ll have a full-sized puppy for quite a few years if you get a Saint Bernard!

Dog Breeds that Take Longer to Mature Mentally
There are some dog breeds that take longer to reach mental maturity, and sometimes never act their age. Some breeds include:
Golden Retriever
The Golden Retriever is known for having a super cheerful personality. They can be very playful and silly. This behavior continues into adulthood, and sometimes even into old age.
If you’re looking for a playmate that’s always willing to play, consider getting a Golden Retriever!
Bulldog
Bulldogs also take time to mature both physically and mentally. These puppies can take about 12 to 15 months to reach their adult size. And their bones can continue to develop for up to 18 months.
Like the Golden Retriever, the Bulldog’s puppyish behavior can last into late adulthood. These dogs are also great tug of war players! So if you like this kind of game, the Bulldog can be an excellent companion.
